    Hi,

    Thanks a lot for your query and we are so sorry about the trouble this must have caused.

    Please delete the plugin and install it once again. It seems like it might not have installed properly.

    If that doesn’t work, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.
    Sensitive Data Section

    It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

    https://wordpress.org/plugins/temporary-login-without-password/

    You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

    https://wordpress.org/plugins/wp-security-audit-log/

    We really look forward to helping you.
